I have installed pcf857 library. for the pcf8574_KO problem due to the i2c address.
now I have changed it as follows :

// Set relay output i2c address
PCF8574 pcf8574_R1(&I2Cone, 0x24, 4, 5);
PCF8574 pcf8574_R2(&I2Cone, 0x25, 4, 5);

// Set digital input i2c address
PCF8574 pcf8574_I1(&I2Cone, 0x21, 4, 5);
PCF8574 pcf8574_I2(&I2Cone, 0x22, 4, 5);

why init mac still failed?

Init pcf8574_R1...PCF8574_R1_OK
Init pcf8574_R2...PCF8574_R2_OK
Init pcf8574...pcf8574_I1_OK
Init pcf8574...pcf8574_I2_OK
